Cement manufacturing is a significant contributor to climate change, responsible for around 5% of total global carbon dioxide emissions, says WADE. The report estimates that on-site power in cement plants has the potential to meet more than 0.4% of total global electricity demand. It is estimated that if the full potential of bottom-cycle cogeneration alone were realized, global annual emissions could be reduced by some 68.3 million tonnes of carbon dioxide. Potential exists for both waste heat recovery and top-cycle cogeneration. Over 2900 MW of installed electric generating capacity in cement plants worldwide is documented in the report.
Calpine Corporation’s Deer Park cogeneration Energy Center in Deer Park, Texas is to be expanded with the addition of a final two combustion turbines. The 1007 MWe, natural gas-fired, combined-cycle cogeneration power plant is located 7 km east of Houston.
